Use a more targeted span when suggesting casting an `fn` item to an `fn` pointer.

Previously we'd point at the whole expression for replacement, instead of marking what was being added.
We could also modify the suggestions for `&(name as fn())`, but for that we require storing more accurate spans than we have now.
